チタン酸鉛合成反応に対する原料混合ゾルへの超音波照射および摩砕の効果

抄録

Ferroelectric perovskite lead titanate is synthesized from titania sol and lead oxide sol via various precursors. Ultrasonication and milling were performed either separately or simultaneously during precursor preparation. By these treatments, agglomerates were significantly disintegrated, with concomitant mechanochemical incipient reaction toward PbTiO₃. Dispersion state of the product precursor is significantly improved when mechanochemical effects are combined with ultrasonication.
